Simple and Compound Interest Calculator
An online SI and CI calculation used in day to day life.
Formula for Interest Compounded Yearly
Total Amount = P(1+(R/100))n
Formula for Interest Compounded Half Yearly
Total Amount = P(1+(R/200))2n
Formula for Interest Compounded Quarterly
Total Amount = P(1 + (R/400))4n
SI [Interest] = (P × R × T) / 100
P [sum] = (SI × 100) / (R × T)
R [Rate/year] = (SI × 100) / (P × T)
T [Time] = (SI × 100) / (P × R)
Where,
C.I = Compound Interest,
S.I = Simple Interest
P = Principle or Sum of amount
n = Time Span in years
R = % Rate per annum
T = Time Span
